Hi All,

I have a radgrid in my web application in which I disable the grid due to some conditions in code, but when the items(rows) exceed the height of grid I am not able to see the content as scrolling is also disabled due to grid being disabled.

I have tried the below code so far in order to enable the RadGrid but set the columns to readonly.

RGSellingEntity.Enabled = true;
                bool ReadOnly = true;
                foreach (GridColumn col in RGSellingEntity.MasterTableView.Columns)
                {
                    if (col.ColumnType == "GridBoundColumn")
                    {
                        col
                        GridBoundColumn boundCol = (GridBoundColumn)col;
                        boundCol.ReadOnly = ReadOnly;
                    }
                    if (col.ColumnType == "GridTemplateColumn")
                    {
                        GridTemplateColumn tempCol = (GridTemplateColumn)col;
                        tempCol.ReadOnly = ReadOnly;
                    }
                }

but it did not work, the thing I want is that the radgrid should be in disabled except :the scrollbars(vertical) so that user can scroll through the items/rows in radgrid.
I need to do this code behind based on some conditions.

Can someone please help ASAP?

Thanks in advance!

I have a stiuation where becuase of how I load the page I need to stick in a fillGrid as boolean = false at the top of the load page to keep the NeedDataSource from firing.  I then turn it to true when it can fire and rebind the grid.  Everything works great up until I need to use the insert of the radgrid and then it bombs out.

hi,

I want to compare two different grid columns data. How can do this on server side. Please provide help full solutions.


Thanks,

Hi all,
I am using the latest version of async control with a handler to upload user images.

The handler code is inside a try...catch statement:
 
    protected override IAsyncUploadResult Process(UploadedFile file, HttpContext context, IAsyncUploadConfiguration                      configuration, string tempFileName)
   {
        SampleAsyncUploadResult result = new SampleAsyncUploadResult();
        result.ImageUri = string.Empty;
        result.ImageID = 0;     
        try 
        {
             .... process image stream......
        }
        catch (Exception e)
        {
            Logger.Error("Error in IAsyncUploadResult Process.....", e);
            result.ImageUri = string.Empty;
            result.ImageID = 0;
        }
        return result;
    }

However, I never see the above error in my log files... Instead I often see the following error, which is logged on the application error even of global.asax:

ERROR 2011-07-19 19:18:47,994 - Application Error by user: 
Telerik.Web.UI.AsyncUpload.AsyncUploadHandlerExeption: RadAsyncUpload handler is registered succesfully, however, it may not be accessed directly.

Can you please help me troubleshoot this problem....

Thank you for your time,

Hi Telerik Team,

We try to find a way to customize the file upload control in the Editor's *.manager. The idea is we want to make two tabs in the file upload window, one is select files from local computer which is the same function as now and we also want to add a new tab for external applications. We will implement the new tab feature by ourselves.

We are struggling to find a solution to add two tabs and implement our customized feature in file upload control. Could you please help us out ?

The interface should look like what we see in the attachment.

Thanks in advance!

Hello Team,
I am using Telerik Version 14.1. I have created simple RadChart in Pie type. But I am unable to show the % of area covered. Can you please suggest how to show the percentage over the chart. I tried a lot & referred so many links. still didn't get. Please help me out.


For the ref i have attached image.


let me know for any query.

aspx page:
<telerik:RadChart ID="RadChart1" runat="server" Width="540px" Height="330px" DataSourceID="SqlDataSource1" DefaultType="Pie" ChartTitle-TextBlock-Text="Summary Chart">
            <Series>
             <telerik:ChartSeries Type="Pie" DataYColumn="Hits" DataLabelsColumn="PageName">
                <Appearance LegendDisplayMode="ItemLabels" />
            </telerik:ChartSeries>
            </Series>
        </telerik:RadChart>
        <asp:SqlDataSource ID="SqlDataSource1" runat="server" 
            ConnectionString="<%$ ConnectionStrings:RPConnectionString %>" 
            SelectCommand="xsp_GetPageRank" SelectCommandType="StoredProcedure"></asp:SqlDataSource><br />

Hi,

Is telerik have default Chart Color Palette  ?  not in system color (AreaChart.PlotArea.YAxis.MinorGridLines.Color =color.white;)

Example :

AreaChart.PlotArea.YAxis.MinorGridLines.Color =ChartColorPalette.AcidWash;

Kannan.

I think a bug might have cropped up into the latest Telerik release (Q1 '14, April SP release). Typically, when clearing and adding items to a combo box client side, script like this has worked:

var combo = $find("MyComboList")
combo.trackChanges();
combo.clearItems();
// code to add items
combo.commitChanges();

However, with the current release, the above code will leave the previously selected item in the combo box as well. In order to remove it, you have to manually clear it, so the above code now becomes this:

var combo = $find("MyComboList")
combo.trackChanges();
combo.clearSelection(); // ensures that the current selected item will be removed as well
combo.clearItems();
// code to add items
combo.commitChanges();

This seems like a bug to me. Can someone from Telerik confirm?

Thanks,

Mike Oliver

Hello,
I'm having couple of RadComboBoxes in my page and one of it is not firing the selectedindexchanged event when the first item is selected. If I select the second list item, the event is firing. Here is my code:

<tel:RadComboBox ID="rcbArea" runat="server" Height="110px" DropDownAutoWidth="Disabled" Width="213px"
                                AutoPostBack="true" HighlightTemplatedItems="true"
                                AppendDataBoundItems="true"
                                EmptyMessage="Select Area"
                                Localization-CheckAllString="Select All"
                                Localization-AllItemsCheckedString="All Divisions Selected"
                                Font-Italic="false"
                                CheckBoxes="true" EnableCheckAllItemsCheckBox="true"
                                OnSelectedIndexChanged="rcbArea_SelectedIndexChanged">
                                <ExpandAnimation Type="OutQuart" Duration="500" />
                                <CollapseAnimation Type="OutQuint" Duration="300" />
